JAMES ri". Downntn'or' GLEN iiiortnf'sjnriwnonf sewing machine, although the device is read twine or wire off4 a spool. f

A particularobject of my inventionis to do away withv a Ywasteful' fault common in practically all devices at present in usewith power machines, that is, when the thread or wire is drawn from a spool, lwhich is centered on a revolvable spindle, thefthread or wire, if it is not drawn off tautly will drop ily adapted to any machine using thread,

down in loose circlets about the lower'end'A of the spool and the spindle as it revolves, will tangle theloose thread oi wire and the operator in orderto clear the tangled thread from. about the spindle will pull offa bunch of the thread and discard it. 'Ihiswaste in a large manufacturing establishment'quickly'assuines large proportions.

Another object of my invention is to pro- Y vide a spindle which will not only grip and hold the spool to prevent it from tending to creep upwardly off the spindle but-will also H hold the spool vertically so that the thread or wire may be .drawnoi witlia minimum of friction, and therefore less liability Vof breakage.

Referring tothe drawing, forming part of my application, in which one embodiment of my invention is disclosed, f v 'l Fig. 1 is a view in elevationof my spool holder, parts thereof. being, shown in section to make illustration more clear; H

Fig. 2.is a side .view ofthe device as shown in Fig. 1;

Fig. 3 is a view in elevation showing the adaptation of my spool holder to a cone, upon which the lighter kind of thread is wound in larger quantities; and

Fig. L1 is a sectional view taken on line 11-4 of Fig. 1 of the brush and holder, showing how the former is maintained against the spool when a quantity of the thread has been removed. Y

Referring to the drawing in detail, 10 denotes in general the spool holder which conl 21 to hold thespool-v 22` firmly inf place.

Marzo si'st'si'rofV vertically disposed post 11-from-V which@l eXtends1-the -ofl'sethuprightlarm 1-2; f' The,` post 1,1 is retained in some suitable partA 13 of a machine'through the-medium loflaA set screw 14l,and -theupper end: ofsaid-post enters, the bore-loof a saddleblock 1GB-which.l 1 f pivotally holds the spool gripping lfingers f .Thesespool gripping fingers '1;7 and 18 pins 20 adjacent their 'bent portions.

theyl are squeezed-together they *will Apass v(l5 are bent intermediate their ends 'so` that-the upper Vends will form tongs whichvtendto open, due to a coiled l retracti-le f spring 19 fastenedto, and extending `between the lowerl f ends ofsaid ngers .17. and 18;---The lingers are pivoted in the hupper slottedfpoi'tionI of/ thel saddlerl throughy they medium of'drirf'ln f 5f* f inner sides of the uper lportions of -the-fin.-l 'gers 17 and 1S are flattened -so that when into the bore 21 vof aI spool-- of? thread-,and

against the action of the spring -19 will ,eX

pand against vthe inner wall of the spool bore Inforder-tovniaintain the spoolv invertical f position, it 'islnecessaryito' provide for the i 'closingA of the linger ends simultaneously andtinorder to'accomplish this, I providea centering pin 23 which is curved to allow' of movements/of Tooth the fingers 17 and 18.

The pin 23 is yproperly peened yto'prevent its fworkingout ofi-positionl and. getting lost.-

This-pin, it will be notedlupon--referen'ce to Fig.V 1, will lonly allow the I lingers 17 l and 18 to close equally so that both willv have tol be moved at once. If only finger 17 was moved,

they. tendency offl that vlinger would be to vthrow the end of the pin 23'` in linger 18 downwardly, thus preventing lmovement-of the finger 17, dueto the j amining ofthe pin in linger 18. f The fingers come together always. on the median line 'of the saddle block Their the thread or wire isunwound from the spool, the adjacent strands to the one being drawn off usually fall down, and off the end ofthe spool to eventually become tangled in the holder.` In order to prevent this, I provide a flat brush element 24: which is soldered or otherwise attached to an adjustable sleeve 25 which can .slide freely up and down the arm 12 and which may be held in any desired position thereon by a wingnut 26 which is carried in the sleeve 25 and' which engages the arm 12. In order to keep the brush against the spool when the thread is partly drawn oi, I provide a spring 25, one end of which is attached to sleeve 25 and the free end of which presses against the brush, which may be pivoted as at 24 to sleeve 25. The brush may be of ordinary stili" hair bristles, ory in the case of a spool of wire may be of stiff wire, and in rubbing against the spool prevents the loose thread or wire from dropping off the spool to subsequently become tangled and wasted.v The brush may be of any width desired, and the pressure of the bristles against the spool is regulated by the wing nut 26.

It is apparent that my holder is equally adaptable for use with the cones and spools common in knitting mills and by bending the upper end of the arm l2 to extend over the cone and forming an eye 27 in the end thereof, through which the thread passes, I provide a means whereby the thread will be supported from above and will therefore not tend to become loose and fall down below the bottom of the cone where it will catch and cause breakage. However, in cases where hardened or wire thread is used on the cones which tend to curl or tangle, my brush device is applied as shown.

W'hat I claim is l. In a device of the character described, a vertically disposed post member, a pair of gripping members pivotally associated with said post member and adapted to hold a spool, an arm projecting from said post and extending parallel to said gripping members, and means on said arm for engaging the periphery of said spool to prevent the dropping off of thread strands from said spool.

2. In a device of the character described, a saddle block, a pair of arms pivoted in said saddle block, and means passing through said arms to cause the ends of the same when brought together, to close on the median line of said saddle block.

3. A spool holder comprising a post member, a saddle block revolubly mounted on said member, spool holding arms on said saddle block, and means mounted remote from said spool-holding arms and adapted to engage a spool held by said arms whereby loose strands of thread will be prevented from dropping oli said spool.

4. A spool holder comprising a support adapted to be attached to a machine part, a saddle revolubly mounted on said support, a pair of gripping members pivotally associated with said saddle, a spool carried by said gripping members and adapted to revolve therewith when the contents of said spool are drawn oli, and means adapted to engage the outer strands of material on said spool whereby the same will be prevented from dropping off of said spool.

5. A spool holder comprising' a support, a saddle revolubly mounted on said support, a pair of tong members pivoted in said saddle, a spring member connecting the lower extremities of said tong members whereby the upper ends thereof will tend to separate, a spool adapted to slip over the upper ends of the tongs, and means associated with said tong members whereby the same will be caused, when closed, to support the spool in the median line of said saddle.

6. A spool holder comprising a support, a spool ot material held thereon, an upwardly extending arm associated with and parallel to said support, and means adjustably associated with the arm with which the material being drawn o is adapted to contact, whereby tangling of the material on the spool is prevented.

7. A spool holder, comprising a support, adapted to receive a spool, a rod associated with said support and adjacent thereto, a wiper element slidable on said rod, and means for releasably securing said wiper element in adjusted position longitudinally of said rod.

8. The combination of a spool support and a wiper support, said wiper support extending longitudinally of the spool support'and having a wiper element associated therewith, and means for releasably securing said wiper element in adjusted position longitudinally of said spool support.

9. In combination, a spool support and means for adjustably mounting a wiper'element comprising a support for a wiper holder associated with said spool support, a wiper holder slidably associated with said wiper holder support, and means for releasably securing said wiper holder in adjusted position longitudinally of said spool support.
